Police identified the driver of the motorcycle as Christopher Kieran Walker, 26, of Kensington, Md. The passenger was identified as Kristen Renee D Bell Wolcott, 25, of Hyattsville, Md.

Police say the two persons, believed to be in their mid-20s, were thrown off a Ducati sport motorcycle when it crashed as they were trying to exit the River Road ramp around 2:50 a.m. Wednesday. It appears that they may have missed their turn and hit a guardrail. Both passengers were killed.

Police say the victims were wearing helmets at the time of the crash, but there appears to be no witnesses.

At 6:48 a.m., the River Road ramp reopened after being closed for several hours due to an investigation.
